Western Bulldogs ruckman Will Minson is risking an early end to his season, after opting to contest his charge of stomping on Sydney midfielder Kieren Jack.
Minson was charged with a level two misconduct offence and collated 225 points and a potential two-match ban for lashing out at Jack in their 82-point loss at Etihad Stadium on Sunday, but could have accepted a one-match sanction courtesy of a five-year good record and an early plea.
Should he be unsuccessful at the tribunal on Tuesday night, Minson will be out of action until 2013 with just two matches remaining this season for Brendan McCartney's side.

All 16 other players involved in the brawl accepted their monetary sanctions, with Essendon ruckman Paddy Ryder the worst of the players hit, as a third involvement in a melee saw him accept a $3000 fine.
